So I understand that your code runs in Linux Kernel. Is it correct? I think the most simple way is to write user space application to work with SUB-20 and arrange communication between this application and kernel module you are writing. To do it directly from kernel is not so simple as it will requi...

Hi,
What you mean by kernel driver? SUB-20 does not require kernel driver.
Do you mean you want to run SUB-20 from withing the kernel?

Man, We have a lot of customers using SUB-20 as I2C master. You are the only one who decided that DLL is wrong. The I2C read of 16 bytes does not fail. The data you read is not the data you've expected. I see two ways to check the reason. 1. Run test I told you before: In any case to be sure I2C is ...

What is exact part number of the EEPROM you use? Read the writing on the IC bag and post it exactly as it written where. ST has a number of different EEPROM types. In any case to be sure I2C is working properly try to write 16 bytes byte by byte advancing all the time Memory Address and writing only...

HI, The problem is not in software (SUB-20 Tool is only written in C++), not in SUB-20 DLL and not in SUB-20 hardware. The problem IS in correct usage of the mentioned ST24C02 EEPROM. Someone had to read first it's datasheet. Our wonderful solution is to reference you to the datasheet of ST24C02. Th...

HI,
I see the 16 bytes are read. The last 11 bytes are ff.
Where do you read from? What device are you communicating with?

HI,
Try to connect Grex output directly to TV and not via DVD Recorder. Tell us if you get clear picture this way.
More likely one of your video cables is not properly connected or has lost wires. To find out which cables you need to split system and see where the problem begins.

HI, SPI Tab is an evaluation of SPI related functions. It is not intended to burn flash like regular programmer. There is another approach to the programmer in SUB-20 Tool: http://www.xdimax.net/forum/viewtopic.php?f=2&t=103&start=0&hilit=programmer I'm not sure it supports SPI flash currently but y...

Grate.

Yes. It's clear now. I think we will implement following function sub_spi_transfer_ess( sub_handle hndl, char* out_buf, char* in_buf, int sz, char* ss_config ), where ss_config will be a string definig SS activity during transfer. For example ss_config="0LL^++LL" 0 - Use SS0 L - transfer byte with S...
